A user is trying to create an EBS volume with the highest PIOPS supported by EBS. What is the minimum size of
EBS required to have the maximum IOPS?
A.
124
B.
150
C.
134
D.
128
Explanation:
A provisioned IOPS EBS volume can range in size from 10 GB to 1 TB and the user can provision up to 4000
IOPS per volume. The ratio of IOPS provisioned to the volume size requested should be a maximum of 30.
The question is outdated, non of the volumes can hit the maximum IOPS. The PIOPS vol range is from 4 GB to 16 TB now, with maximum of 20,000 iops per vol.

Agree. You would need at least a 667GB volume to max out at 20k IOPS

isn’t the ration also increased to 1:50.So I guess a 400GB would do right

The link shows that we can provision upto 4000 IOPS per volume
So the answer will be C

Ans should be 400. Its updated to 50:1 now
An io1 volume can range in size from 4 GiB to 16 TiB and you can provision up to 20,000 IOPS per volume. The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1. For example, a 100 GiB volume can be provisioned with up to 5,000 IOPS. Any volume 400 GiB in size or greater allows provisioning up to the 20,000 IOPS maximum.

400GB, question is outdated (20000/50) but good to keep in mind.
